CDuce project is a modern XML-oriented functional language with innovative features. A compiler is available under the terms of an open-source license.

CDuce is type-safe, efficient, and offer powerful constructions to work with XML documents.

Here are some key features of "CDuce":
XML objects can be manipulated as first-class citizen values: elements, sequences, tags, characters and strings, attribute sets; sequences of XML elements can be specified by regular expressions, which also apply to characters strings;
functions themselves are first-class values, they can be manipulated, stored in data structure, returned by a function,...
a powerful pattern matching operation can perform complex extractions from sequences of XML elements;
a rich type algebra, with recursive types and arbitrary boolean combinations (union, intersection, complement) allows precise definitions of data structures and XML types; general purpose types and types constructors are taken seriously (products, extensible records, arbitrary precision integers with interval constraints, Unicode characters);
polymorphism through a natural notion of subtyping, and overloaded functions with dynamic dispatch;
an highly-effective type-driven compilation schema.
